I'm planning on setting up a membership site to teach an online course. I want my students to see me in much the same way as students attending a lecture would - in front of a screen & pointing out stuff out while explaining it. I see three possible ways of doing this but am not sure of the likely success of each...
1. Buy a greenscreen kit off ebay for ~$350 & then key in a camtasia video using Vegas. My worry here is that the muslin in these kits is not dense enough & keying will be difficult
2. Paint my backdrop wall green using special chroamkey paint & then key in a camtasia video using Vegas. Problem is that there is a door in the middle of the wall & I'm worried about shadows from the door cavity.
3. Buy a computer projector and project my lesson material onto a white screen & then video myself explaining things. This is my preference because it will mean less editing. However I'm worried that the projected image will video OK, but that the camera will have problems picking me up on the side.
Be grateful for some feedback.
